In terms of the core gameplay, Space Marine's approach is almost completely at odds with Epic's franchise: for a start it's not a cover-based shooter, instead melding third person blasting with highly satisfying melee combat a touch reminiscent of Dynasty Warriors. THQ's Warhammer 40,000: Space Marine may well have picked up some bizarre, unflattering press recently for its superficial similarities to Gears of War, but our experience of the recently released playable demo is almost entirely positive with the game offering up an intriguing spin on the established third person shooter formula.
